I previously had problems with mono line (spinning). After doing some digging for info, I was lead to believe that a braided line is the way to go. After receiving the new (braided) line, I did some preliminary casting, etc., to try it out and yes it certainly came off the spool easily, adding distance to my normal casting stroke plus it has minimal visibility in the water. And needless to say, despite thickness like thread, the line was really strong.

However, after a four day fishing trip for "Silvers/Coho" salmon in Alaska I can tell you this line has some problems.
Granted, we fished long hours each day on a river thus continuous casting/retrieving. And we had good luck in terms of catching fish. Now to the line. Attaching line to lure, I used double swivel, etc.. Despite this, I had several instances of suddenly having a twisted mess of line about 20 > 30 feet above the lure. Two times the twisted mess was so tight and the line so thin, I could not untangle and had to cut off that much line. Also, I began to notice the line was changing color in several area. Close examination it appeared to be fraying and in one case I broke the line via pulling by hand. The line apparently has poor abrasion resistance. And finally, using a barrel knot to attached the line to a swivel, etc.; Initial pull on line to test knot, A-OK. But after losing a lure during a cast, I brought the line back in and the end has several twists and a frayed end. Again, I believe this was abrasion on tension areas of the line in the knot. My solution, every hour or so, pull the lure in, hole lure in one hand, line in other and pull as hard as you can to test the know. Twice I broke the knot and had to retie the line to the swivel.

So be aware. I was using 30 lb. test line; perhaps I should switch to heavier braid such as 50 or 60 lb?

Just about everything you've told us about it really inconsistent with braided line. At least with any braided line I've ever used. Nylon is tougher than just about anything. But you are right about one thing, braided line does not knot well. Any knot that relies on coil upon coil for strength is subject to cutting through itself with braid. The top coil cuts right down through the lower coil. Even if you use a knot similar to the clinch or improved clinch, you better take the time to make sure the wraps are laid out evenly and that they draw up correctly as you tighten it. If at all possible use a palomar knot. I know guys who carry a small vial of super glue and they religiously put a tiny dab on every knot they tie in braid. I can't say braid doesn't color fade but in my experience it is a gradual thing and if a line fades right away or all at once I'd say you've got a "batch" problem. I have a spool of Spider Wire that has to be 20 years old (I bought a huge spool of it when a bait shop went outta biz) and it is still as ugly green the day they put it out and I'm sure you could haul timber with it. Lastly, the guys on "Salt Strong" did a video of how many twists in a line occur before you ever get the benefits of a swivel. The smaller the line the longer it will take before you roll that swivel the first time. Consider using chain swivels. Other than that, I think you just happened to be the unluckiest guy who ever tried braid for the first time and got caught by truly off-beat circumstances.

Great comments thus far from everybody! Glad to hear that you had success on those Alaskan waters nevertheless and got by with what you were loaded up with in the line department!

Hopefully something that has been said will become the cure on this issue for you. It's kind of a funny thing...way back in the 40's thru 50's or so...braided "dacron" line was the "go to" line formulation. Then along came monofiliment. It was a miracle line by most accounts, and dominated the world for many decades. Then, as if we had made a brand new discovery...braid was back...only very high tech and in a myriad of manifestations!

I am not trying to get any rotten eggs thrown my way, but I've been using "mono" all my fishing life, in various lb test strengths from 4 to 50 and it has done very well by me for all of the fresh and saltwater fishing I have ever done. I'm not a pro, or commercial charter guy...so my experience is only personal. 95% of my rods are set up with mono, but I do have a few with braid...honestly, I don't really like braid, but it does perform for me just like mono. My best application is when I'm jigging down deep in say 100' of water. Also works very nicely on my dipsey diver dedicated salmon rods. The low stretch factor is definitely nice...but I still catch fish when deep jigging with mono too! Sorry if my comments offend anybody...that is not my intention...OK, I'm going to duck now and run for cover!
